 # This file contains suppressions for the Dr.Memory tool, see
 # http://dev.chromium.org/developers/how-tos/using-drmemory
 #
 # This file should contain suppressions only for the reports happening
 # in the 'full' mode (drmemory_full).
 # For the reports that can happen in the light mode (a.k.a. drmemory_light),
 # please use suppressions.txt instead.
